摘要： This invention relates to an electron multiplier unit and others enabling cascade multiplication of electrons through successive emission of secondary electrons in multiple stages in response to incidence of primary electrons. The electron multiplier unit has a first support member provided with an inlet aperture for letting primary electrons in, and a second support member located so as to face the first support member. These first and second support members hold an electron multiplication section for the cascade multiplication and an anode. The electron multiplication section is comprised of at least a first dynode of a box type and a second dynode having a reflection type secondary electron emission surface located so as to face the first dynode and arranged to receive secondary electrons from the first dynode and to emit secondary electrons to a side where the first dynode is located. The anode is located at a position where the secondary electrons emitted from the first dynode do not directly arrive, and the second dynode alters a travel path of secondary electrons so as to be kept in a space between the first and second support members.

摘要： To eliminate a distortion of an output image detected by a semiconductor device serving as an anode in an electron tube, a faceplate is configured to a planar shape and a window provided on the semiconductor device has a pincushion outer profile in which points on the outer profile of the window that correspond to points on the outer profile of the faceplate are outwardly positioned farther than the corresponding points in the outer profile of the faceplate that are apart from the center of the faceplate. Further, the window is divided into a plurality of segments to define picture elements.

摘要： A photomultiplier for converting an incident weak light into multiplied electrons to thereby output an electrical signal corresponding to the intensity of the incidence light. The photomultiplier comprises a photocathode for emitting primary electrons; plural dynodes for emitting secondary electrons in response to incident of the primary electrons and multiplying first secondary electrons passing between the dynodes; and shield means for preventing second secondary electrons emitted from a first dynode of the dynodes toward the photocathode from returning to the dynodes, thereby to reduce the generation of a residual pulse currents caused by the second secondary electrons and to accurately detect a main pulse current caused by the first secondary electrons.

摘要： An ASL is associated with an APP module having as a communication target an existing APP SW-C(1). A buffer part accumulates data to the existing APP SW-C(1) and data from the existing APP SW-C(1). A communication processing part transmits the data to the existing APP SW-C(1) accumulated in the buffer part to the existing APP SW-C(1), receives data transmitted from the existing APP SW-C(1), and stores the received data in the buffer part. An API processing part receives as input from the APP module data to the existing APP SW-C(1), stores the data received as input in the buffer part, receives as input from the buffer part data from the existing APP SW-C(1), and outputs the data received as input to the APP module.
